Translated title:
PROPERTIES OF SEISMIC S CODA WAVES FROM STRONG EVENTS IN CENTRAL GREECE USING THE METHOD OF NON – EXTENSIVE STATISTICAL PHYSICS.
Summary:
In this thesis we will study seismic coda waves (S coda), created by strong
seismic events in central Greece. Wave surges are interpreted as scattered
seismic waves created by heterogeneities within the Earth, i.e. fault lines, crack
structures, micro cracks, speed and/or density limits/anomalies, etc. Due to the
nature and complexity of the path of the coda waves we will use non-Extensive
Statistical Physics (NESP) to study the probability density functions (probability
density functions or pdfs) of the coda seismic wave flows. The purpose of the
analysis is to show that the time series describing the fluctuations in the seismic
coda waves diverge from the Gaussian description and their corresponding
probability density functions could be adequately described by the q-Gaussian
distribution. An attempt will be made to interpret the results based on the
theory of coda wave generation as described in a series of work by Sato and
collaborators on the form of coda waves that creates a scattering distribution
that follows an asymptotic force law.
